If 28% of the nucleotides in a DNA molecule contain the base T, what percent will contain the base G

22% base G

Explanation:

background info

nucleotides pairs:

T-A (thymine- adenine)

C-G (cytosine- guanine)

because they are pairs, there is an equal amount of T and A. and an equal amount of C and G

# of T= # of A

# of C= # of G

solve

28% is T, then 28% is A

28*2=56%

100-56= 44%

44% left for C and G

44/2=22 (because C and G amounts are equal)

22% C and 22% G

b. heterotroph

explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
